GlassWire is described as 'Visualizes network activity, alerts on suspicious behavior, manages firewall rules, reports new app connections, and identifies potential threats' and is a very popular Network Monitor in the network & admin category. There are more than 50 alternatives to GlassWire for a variety of platforms, including Windows, Mac, Linux, Android and iPhone apps. The best GlassWire alternative is simplewall, which is both free and Open Source. Other great apps like GlassWire are Portmaster, Little Snitch, Fort Firewall and TrafficMonitor.
